Hello!

I have a mac pro 2010. It has a new 500 GB SSD (i had a flaky one) as a boot drive, a 3TB WD Black for data, and a 5 TB drive for backups. I updated from Sierra to Mojave and now the time machine wants to do a full backup and its saying there is not enough space. The only change was the SSD Mac OS and the data drive is untouched. How can i convince time machine to back up without starting over? I did search but cannot seem to find a solution. Any advice would be helpful.

The reason the Time Capsule wants to do a full backup is because of the new installed OSX. If your are happy with Mojave then allow it to backup and it will delete older backups as necessary. Otherwise I think the only alternative for you is to exclude the system files from backing up on the Time Capsule.
